摘要：在圆柱面上创建与加工3D曲线导槽，建模与编程加工过程复杂，特别是槽顶与槽底宽度一致且槽底为平面的柱面导槽，造型与加工难度更为突出，很多工程软件都难以甚至无法完成造型及编程。通过对SIEMENS NX三维建模与多轴编程加工技术的研究，以柱面曲线导槽为例，分析其形状结构与加工工艺，在NX平台下，介绍了建模与两种编程加工方法，实现了曲线导槽从3D造型设计到编程加工一体化。

Abstract：On the cylinder is created with the guide groove machining 3 d curve, the modeling and programming process is complex, especially the tank top and the bottom of the channel width is consistent, and the bottom of the channel for the flat cylindrical guide groove, modelling and processing difficulty is more outstanding, a lot of engineering software is difficult to can't even get to modelling and programming. Through many years of SIEMENS NX 3d modeling and multi-axis programming processing technology research, curve of cylindrical guide, for example, to analyze its shape structure and processing technology of the NX platform, introduces the modeling method and two methods of programming and processing, guide the curves from the 3 d modelling design to programming and processing integration.
Key words：four-axis machining；curve projection；drive surfaces；tool axis
